The parts of an addition example are the first addend, the second addend, and the sum.
When the program starts, you will be asked to identify the first addend and then the second addend. The program will not continue unless each addend is correctly identified. You will then be asked to add each addend for the sum.
You can see from the picture that the first addend is 2 2/6 units in length and the second addend is 1 2/6 units in length. The sum will combine these two lengths for 3 4/6 units.
To calculate the Sum first add the whole numbers 2 and 1 to obtain 3 for a whole number. Then add the numerators of the fractions 2/6 and 2/6 to obtain the 4/6 in the sum. You may enter 3 4/6 or the simplified form 3 2/3
You may prefer to work vertically:
You may prefer to write each addend in fraction form first as in this example:
You may enter the sum in fraction form or mixed number form. In the above example 22/6 or 3 4/6 are both acceptable.
Follow the directions in the dialog box after pressing the <START> button. The <EXPLAIN> button may be pressed after you enter the second addend to see how to do the example.
After you enter the sum you may press the <REPORT> button. The report will ask for your name but you may submit a code for your name. This report will give the same results as on the dialog box. The report may be printed or e-mailed.
